Abstract

A cosmetic composition suitable for topical application is provided. The cosmetic composition comprises: a safe and effective amount of a humectant; a safe and effective amount of a lipid bilayer structurant, and a safe and effective amount of a chaotropic agent. The chaotropic agent denatures the cross-linked proteinaceous layer sitting immediately above skin thereby increasing the amount of humectant and lipid bilayer structurant that enters the stratum corneum; the humectant binds together with water molecules and the lipid bilayer structurant knits together the lipid bilayers of the stratum corneum thereby preventing water loss.

Description

FIELD OF THE INVENTION[0001]The present invention relates to skin care compositions that provide enhanced hydration while maintaining a good sensory experience during application. Specifically, a skin care composition is provided comprising a humectant, a chaotropic agent and a lipid bilayer structurant.BACKGROUND OF THE INVENTION[0002]Consumers have long desired hand, body and face lotions or creams which, when applied to the skin, improve the condition of the skin while simultaneously providing a pleasant tactile experience. In response to this, numerous cosmetic compositions have been formulated through the years to exhibit satisfactory spreading, feel, lubricity, and absorption upon application to the skin. More recently, consumers have been introduced to specialty lotions and creams formulated to treat dry skin conditions, known as “dry skin formulations”.[0003]A dry skin formulation described in U.S. Pat. No. 4,389,418 uses petrolatum or mineral oil as an occlusive emollient a...
